ORCHARD-PLOW.

Specification of Letters Patent.

Patented Aug. 4, 1914 T 0 all whom it may concern:

Be it known that I, DANIEL HARVEY, a subject of the King of GreatBritain and Ireland, residing at Whitehorse Road, in the post town ofBox Hill, a suburb of the city of Melbourne, in the county of Bourke,State of Victoria, Commonwealth of Australia, have invented a certainnew and useful Improved OrchardPlow, of which the following is aspecification.

This invention relates to implements used particularly for plowingorchard land.

Hitherto with some types of orchard implements it has not been possibleto plow closely beneath the branches of the trees as the horse andplowman can not conveniently pass beneath the same. In consequencestrips of land beneaththe trees have had to be overturned by hand whichhas absorbed much time and labor.

The object of this invention is to provide a plow by the use of whichmuch more of the land can be overturned and laborious manual digging bethereby obviated. By the invention the land may be plowed up to thebutts of the trees, the horse and plowman passing clear of the branches.A plow according to this invention, may for ordinary work be used as acommon implement which follows directly behind the horse but it may bespeedily changed to one which plows to either side of the animal and itsdriver and beneath the branches of the trees. The plow is light ofdraft, easy to manipulate and simple yet strong in construction.

Referring to the drawings which form part of the specification, Figure 1is a perspective view of a plow beam according to the invention. Fig. 2is a perspective view of a bracket and pivot pin carried thereby. Fig. 3is a perspective view of a clevis, a pivot pin and a retention pin. Fig.4 is a perspective view of a segmental draft bar and retention pin. Fig.5 is a perspective view of a draft chain and appurtenances. Fig. 6 is aperspective view of a double headed wedge. Fig. 6 is a view of amodified clevis applicable to the front of the plow beam. Fig. 7 is aperspective view of the lower ends of two handles, separated forconvenience ofillustration. Fig. 8 is a perspective view on a reducedscale of a plow according to the invention. a r

The invention includes a supporting wheel 2 mounted upon an axle 3carried by a stem 4. At the upper end of the stem is a suitable clamp orother retainer 5. Behind the supporting wheel is a plow share 6 of anydesired construction. Adjoining the share 6 is a suitable mold board 7to which are attached the lower ends of standards 8 and braces 8. Abovethe supporting wheel 2 and share 6 is a beam 9 having a front end i anda rear end. Formed through the front end of the beam 9 is a pivot pinhole 10. Depending from the front end of the beam 9 is a segmentaldownward extension 11 in which is a series of adjusting holes 12. At therear end of the beam 9 is an upward extension 13 having at its extremitya bridge 14, depending from which is a fold 15. Formed through the rearend of the beam 9 and through the fold 15, below the bridge 14, is atransverse slotway 16. Beneath the bridge 14- is a wedge passage-way 17.

With the plow beam is used a clevis consisting of two legs 18 eachhaving in its rear end a pivot pin hole 19 accommodating a pivot pin 20.This passes through the hole 10 in the plow beam. Formcdin the front endof each of the legs 18 is a locking pin hole 21. accommodating a lockingpin 22. This passes through one of the holes 12 in the segmentalextension 11. At the front end of the legs 18 is a bridge 23 havingtherein a locking pin hole 2 1. Beneath the bridge 23 is'a transverseslotway 25.

Passing through the transverse slotway 25 is a segmental draft bar 26having therein a series of adjusting holes 27. Passing through one ofthe holes 27 and through the locking pin hole 24 in the bridge 23 is alocking pin 28. This may be retained to the draft bar or any other partof the implement by a suitable chain or other flexible connection, if sodesired.

With the foregoing is used a vdraftchain 29 having at its rear end a barlink 30 formed through which are pin passage-ways 31 accommodating aretention pin 32. The pin 32 also passes through one of the ad justingholes 27. Pivotally connected to the bar link 30 is a link 33 to whichis pivotally connected the front end of a draw bar 34:. Pivotallyconnected to the rear end of the draw bar 34 is a link 35 byfiwhic'h thedraw bar is pivotally connected to a two pocket shackle. This consistsof a bridge 36 at each side of which is a link pocket 37. At the rear ofeach pocket 37 is an eye ring 38. Passing through the eye rings 38 andthrough the plow beam 9 is a pivot pin or bolt 39.

Secured to the plow beam 9 by means of a clamp 40 or the like is asuitable colter 41. This depends in close proximity to the plow share 6.

Mounted or otherwise secured to the plow beam 9 at. or near the rearthereof is a bracket 42 carrying an upstanding pivot pin 43. l/Vith theforegoing are used two steering handles 44. At the lower end of eachhandle 44, anclpreferably integral therewith, is a foot or lug havingtherein a pivot pin hole 46. The pivot pin 43 passes through the saidholes 46'. Extending between the handles 44 at or near the lower endsthereof is a segmental adjusting-bar 47 Also extending between thehandles 44 may be suitable cross stays 48. The segmental bar 47 passesthrough the transverse slotway 16' before described. Above the said bar,beneath the bridge 14 and passing through the wedge passage-way 17before described, is a wedge 49. This may be provided at each end witha. hammer head 50 or the like.

Instead of the segmental downward extension 11 and pivoted front piececarrying the segmental draft bar 26, a forward piece may be used. This(Fig. 6*) consists of two 'legs 51 each having a bolt hole 52 therein bywhich the said forward piece is bolted to the front end of the beam 9.Integral with one of thelegs is a protuberance 53 having there in a stemhole 54 and provided with a jam screw 55. Depending from the front ofthe forward piece is a downward extension 56 having therein a pluralityof transverse slotways 57 Formed in the front of the forward piece is avertical pin passage 58. In the modification the clamp 5 is dispensedwith the stem 4 of the wheel 2 passing through the hole 54 and beingretained by the screw 55. The draft bar 26 passes through one of theslotways 57 and maybe retained by a pin or the like passing through thepassage 58 and one of the adjusting holes27.

With this invention when the handles 44 are turned upon the pivot pin 43to the left hand side of the beam 9 and have been locked in position bymeans of the wedge 49', and the segmental draft bar 26 has been ad'-justed to the left side of the beam 9 and locked in position by thelocking pin 28, and the link has been placed in the left link pocket 37,and the. bar link 30. has been locked in position by the retention pin32 upon the draft bar 26, the land may be plowed right up. to the buttof almost any fruit or citrus tree. This operation with the partsadjusted as described is known as plowing on. When the handles 33 areturned to the right hand side of the plow beam 9 and the draft has beenadjusted to the right hand side of the said beam the ground may also beplowed right up to the butts of the trees. This right hand operationvconstitutes what is known as plowing off. The furrows meet between thetrees leaving nothing unplowed except perhaps a small V shaped pieceagainst each tree butt. It will be readily seen that to move the draftto either side of the plow beam is a simple operation which onlyrequires the slackening of the nut upon the pivot pin 39. The shacklemay then be raised and the link be passed across the bridge 36 andplaced in the opposite pocket 37. The bar link 30 is removed from thedraft bar 26 and the said draft bar passed through the transverseslotway 25. It is then locked in position by means of the pin 28. Thebar link 30 may now be placed upon the draft bar at the opposite side ofthe plow and be locked to the said bar by the retention pin Verticaladjustment of the draft is pro.- vided for by means of the segmentaldown ward extension 11, it being only necessary to place the locking pin22 in the adjusting hole 12 desired.

In the modification to vertically adjust the draft, the bar 26 is placedin the desired slotway 57 and locked therein by a pin or the like. Themodification also permits of the supporting wheel 2 being disposednearer the front of the plow beam and prevents any alteration inthelongitudinal position of the wheel as regards the beam, when beingadjusted.

Having now described my invention what I claim as new and desire tosecure by Letters Patent is 1. In combination, a plow beam, a draft barpivoted to the plow beam, an element pivoted to the plow beam andprovided with a loop which straddles the top of said beam, a linkengaging the loop on one side of the plow beam and adapted to be shiftedfrom one side to the other of the beam and off the center of same, aconnection between the link and the draft bar, handles on the beam, andmeans for shifting the handles from one side or the other of the centerof said beam, according to the position of the loop.
